faults. Another small area of gneiss appears about five miles north- 
west of Chintapilly immediately below the lofty ridge running from the 
Pulichinta hill northwards. This area is also brought in by faults. 
Of outliers of the younger metamorphic rocks only three oceur—the 
Congramulla four miles and a half east-by-south of 
i qa Juggiapett, and the broad low dome-shaped hill 
one mile and a half south-west-by-west of Achammapeta ; the third out- 
lier is a very small one, only a few acres in extent, lying immediately 
north of the extreme north end of the Achammapeta hill. 
Some obscurity exists as to the geological horizon to which these

formation, the lowest division of this younger metamorphie series, as 
shown to the west of Nakarikallu.

Rene: ably on the Juggiapett quartzite and interme- 
diate slate bed, are considered as an extension of similar limestones 
occurring north and north-west of Nakarikallu which Mr. King regarded 
as equivalents of the Jummulmudgoo limestones, a member of the 
KARNUL formation, which in the Kurnool district lies unconformably 
on the KADAPAH formation. 
Should these limestones prove to be Jummulmudgoo, I cannot think 
but that the northward extension of the Nakarikallu set of rocks of the 
KADAPAH series must stop short with the Biravallipaya dome. I certainly 
could not trace any signs of unconformability between’ the Palnád lime- 
stone series and the Juggiapett quartzites and slates; and, if these are
